Benefits of technology

The present invention provides the advantage that it can isolate two antennas from each other, even when their resonant frequency bands overlap. This allows the antennas to be placed close to each other without affecting their properties and performance. For example, two antennas in a mobile device can be placed very close to each other, reducing the size of the device and providing space for other components.

Problems solved by technology

Where the antenna arrangement includes two or more antennas, the antennas may electromagnetically couple and interfere with one another.
Consequently, where the antenna arrangement is required to fit into a relatively small space, the antenna arrangement may be inefficient or even inoperable.

Abstract

An apparatus including a first port configured to receive signals from a transceiver and to receive a first antenna; a second port configured to receive signals from a transceiver and to receive a second antenna; a first reactive component coupled to the first port; a second reactive component coupled to the first reactive component at a first junction and to the second port, wherein at least the first reactive component is configured to have an impedance that shifts the phase of a first signal, in a second operational resonant frequency band, received from the first antenna, and the second reactive component is configured to have an impedance that shifts the phase of a second signal, in the second operational resonant frequency band, received from the transceiver, so that the first signal and the second signal at least partially destructively interfere with one another at the first junction.

Description

FIELD OF THE INVENTION[0001]Embodiments of the present invention relate to apparatus, methods, computer programs and computer readable storage mediums. In particular, they relate to apparatus, methods, computer programs and computer readable storage mediums in a mobile cellular telephone.BACKGROUND TO THE INVENTION[0002]Apparatus, such as mobile cellular telephones, usually include an antenna arrangement for wireless communication. Where the antenna arrangement includes two or more antennas, the antennas may electromagnetically couple and interfere with one another. The electromagnetic coupling / interference between antennas increases as the distance between the antennas is reduced. Consequently, where the antenna arrangement is required to fit into a relatively small space, the antenna arrangement may be inefficient or even inoperable.[0003]It would therefore be desirable to provide an alternative apparatus.BRIEF DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION[0004]According to ...
